6.2.3 Sea water corrosion ~

alVtIniccou les.

Since sea watei is a

good

electrolytic

- ~e dissimilar metals and alloys in

onductor, an=i=t is common pract ce to co

structures exposed to sea water attack, galvanic corrosion 1s encountered quite frequently.

Galvanic action in sea water follows the general laws of galvanic corrosion.

Kowever,

the calcium, magnesium, and strontium present in sea water tend to precipitate as carbonates

on cathodic surfaces.

The effeet of such precipitated

deposits,

Plus heavy growths

of Marine

organisms, is to stifle the galvanic effect and to distribute the galvanic protection over

larger areas of cathodic surfaces than would be the case in their absence. Marine

growths

also tend to distribute galvanic action over the anodic

surfaces

by interposinga common

resistance

which reduces the relative impc.rtanceof the initital resistance of the electrolyte.

On the basis of practical experience and experimental observations, the table (table II

herein) bas been constructed as a qualitative guide to what may be expected when different

metals and alloys are combined with different area relationships in sea water exposure.

The.

common materials have been arranged in a galvanic

ser ies

with respect to sea water.

In the

case of active-passive materials, like the stainless steels, it has been assumed in the table

that

these

alloys may suffer accelerated corrosion when in contact with all materials more

noble

than their active state and that they may accelerate corrosion of.all

materials less

noble than their passive state.

In other words, the table tends to err in the safe direction.
